To all whom it may concern:

Be it known that 1, 'Lannniqo'a s. Laos- MAN, a citizen of the United States, and a resident of New York,.inthe county of New York andState of New York, have mve'ntedf certain new and useful Improvements in Sash or Frame Construction, of which the followin is a specification.

My invention re ates to window sash or frame construction and particularly to the manner of securing and locking the intersecting members, together aswell as to the construction of the oint itself.

The invention is particularly adapted for and useful in 'oonstriuctin metal window sashes and frames but-it will be understoodthat its application is not limited to this use as the utildty is of wide scope and applicable to any.suitable metal manufactures. The object of the invention. is to provide a simple, cheap and efilcient means for looking intersecting members to each other.

In the accompanying drawings, Figure 1 is a plan view of intersecting members prepared for securing together in accordance with this invention. Fig.2 illustrates the parts of a frame prepared in accordance with this invention and arranged one above the other in the relation in which they are assembled, parts being shown in cross-section. Fig. 3 is a cross-section through the finished joint. Fig. 4 is a plan view of the flange 'forn'iing a finished joint. Fi 5 is a plan view of one of the frame mem ers illustrated in Fig., 1. j4: of each member lie in 'the' same plane; q 1 When so placed the miters 6 of each member engage and the Fig. 6 is a plan view of a modification in the form of opening made to expose the'webs of the intersectin members.

In the draw ngs 1 and 2 indicate metallic-- intersecting members of a structure daisy may be a window sash, frame or other sm'n lar deviceh The members 1 and 2 'each consist of a strip of metal having a web-portion 3 and a flange or flanges 4 rojectin therefrom and are preferabl ma e of stan ard shaped parts owing to t e cheapness of them over speciall' formed members and the facility with w ichvthey can be obtained. Preferably the said members are T-sha ed in crossseotion assuch shape is especial y applicable for use in construction of window ,sashes or frames, the angledigween the web and each p ket for the reception of may also be Securing material.

Each of the members 1 and 2 at the point Patented June 1e, 1914.

the "window pane and putty or other or points of desired intersection is cut-away so as to expose the upper-ed e' of the-web; According to one method 0 -.-carrying-the invent-ion into eflect, the flanges 4; are cut away or removed py ais'tampingflo peration from each sidofiftheweb' 3 as" indicated in I a Fig. 5, m this case the opening having an,

arc'shaped edge 5 and a miter 6. The spe cific form taken by thecutyout portion of the flange 4 is immaterial to this invention,

Fi 6 in whichthe flanges are cut-away at rig t angles to the webqandof-a width equal to the width of the flange 4. j

v The parts may be removed, desired, by a simple stamping o eration and as the another form of opening being-illustrated in I flanges on both themem ers'j'l and 2 are cut T e webs of the members 1 and 2 are also awa alike but one set of dies are necessary. 4

each slotted in a place in line with the cen-''' ter of the removed arts of the flanges 4.

For instance, the we 3 ,ofIthe member 1 is provided with a slot 7 entering from the lower edge of the web and of a width equal to the thickness-of the web while the web 3 of the member'2 is provided with a similar; 1 slot 8 entering from the top edge of the web, the slots '1 and 8"being of suflici'e'ntdepth that when the members ,1 and -2 are placed crossing each other withv the slots in me theycan be inter-meshed until the flanges members appear as shown in Fig. 1.

9 indicates a metallic button-101' c'oii'ne'c- 'tor of'any desired design and provided with welding projections depending from its under surface preferably in theform of. a cir-' pointed lug or pin 11,

ton intersecting the edges of thewebs at dour points about the intersection. -These intersecting points of ridge'and-webs form l isolated points of contact which allow the parts to be. readily and quickly joined by the electric welding process.

By welding the partsv together, a perfect,

strong bond between the sash .or frame members as well as simplicity and beauty of finish is attained. I i I To electrically weld the button 9 to the members 1 and 2, the parts are held between the electrodes of a suitable electric welding :erably through the electrodes, to fo parts together and complete the weld," Asmachine a'ndcurrent is passed from one elect-rode to the other through the work at the same time pressure being appliedgprefl the the electric current. passes from the members 1 and 2 to the button 9, the points of isolated contact formed by the intersections of the ridge 10. and exposed edges of the webs 3 soften and by the application of the pressure coalesce with each other andform four oints of Welded union around the intersect.-

mg webs. The electric weldin'gjprocess bein now so well understood and so universafiypractised, it isthought that any further specific descriptionfof its use in thisinvention 1s unnecessary. -30.

It will be understood that the type of intersecting members herein set forth is for the purpose-ofillustration only and that various modifications and equivalents of the parts.

herein. shown might 'be. resorted to without departing from the spirit of the invention; 3,

What I claim as my invention is i 1.-Themethod of makinga s a-sh or frame joi'nt-consistin in providing flanged strips,

. cutting away t e flanges of saidstrips at the :point of intersection toexpose the 'web,.placmg abutton 'over such intersecting webs and we ding said button thereto.

' 2. Themethod of making a'sash' orframe joint comprisingintersectin flanged strips, consisting incuttlng away t e flange of said strips to-expos'e. the webs at-the intersection and electrically. welding a button to said The method of making a sash or frame oint comprising intersectin flanged strips consisting in cutting away t e flange of sai strips to expose the webs at the intersection, superimposing a button havin weld' P j-ections laced in contact wit said exposed webs and electrically welding said ,button to said webs by said projections.

4. The method of making-a sash or frame joint comprising intersecting flanged strips,

consisting in cutting away the flange of said strips to expose the webs at the intersection, superimposing a ridged button over saidmtersection with the ridge in contact with said webs and electrically welding said button flange.

6.'A' sash .or frame joint comprisin flanged strips intersecting each other wit the flanges'in the same plane, said flan cut-away at the intersection whereby the 1ntersecting webs of said strips are exposed and a button spanning said intersection and 1 welded to said webs at eachside of the ter'section.

7. A windowsash or frame comprising T- shaped intersectin members arran ed wlth the flanges of. said members in t e same 1 plane, the flanges of each member bemg cut away and the intersecting edges of the web exposed adj acent thereto and a ridged button welded t ereto by said ridge. v
